不太明白其中的COM中断（还是事件），需要怎么去设置。

大神帮我看看，主要是主函数，这是模拟的一个6路PWM的换向，是不是可以实现其功能。
我不太明白他的COM事件的意思，谢谢指点。
void main(void)
{
Tim1_Init();
while (1)
  {
for(step=1;step<7;step++)
            {
                     Commutate(step);
                     TIM1_GenerateEvent(TIM1_EVENTSOURCE_COM);

            }
}
}

void Commutate(u8 step)
{

      switch(step)

      {
      case 1:    //3H、2L//       WH OFF  WL OFF

                     TIM1_CCxNCmd(TIM1_CHANNEL_1, DISABLE);

                     TIM1_SelectOCxM(TIM1_CHANNEL_2, TIM1_FORCEDACTION_ACTIVE);

最后程序实现了吗

这个看着好复杂……

你是要控制步进电机吗？

com事件其实就是定时器的up中断,特殊的情况是用户可以操作代码生成这个事件
